Abis it's going to be very difficult for you with pigs' insane level power that high. And playing on normal mode gives you only one third the reward of insane mode, so levelling birds beyond level 80 is going to be a drag. Imo u can make another account and play story mode only till u unlock the red dungeon. I made this same mistake n had to start again similarly.

I'm not sure. But maybe around 10000 on unlocking red dungeon. Then go no further. U can cross that 10000 mark if you continue levelling up your birds for a couple weeks (I believe your team power is 3200, not 32k). Yes it is extremely important to play insane mode not only for self but the team as well. Take the present event as example. At 2600 skulls u get one golden ticket. On playing insane mode u can get that by day 4. But it is not possible on easy n hard modes. Also the team loses out on those skulls
